455480R

The 4554 80R is a current and voltage monitor relay with output. These monitors provide a digital indication of the monitored load current and/or voltage levels. The relay contacts are energized when the monitored levels reach a preset setpoint. It’s commonly used in networks, power systems, and electrical equipment.

The 4554 80R monitor is typically used to provide over-voltage protection, to prevent overloading of a system or application with excessive current or voltage, as well as to monitor temperature and act as an earth leakage protection device. It has a large operating range from 0 to 100V DC or 0 to 40A AC, and can be used for single-phase applications or phase balanced load applications. It is also capable of continuous monitoring, offering adjustable time delay for the output signal.

The 4554 80R features a circuit protection system, allowing it to detect critical situations that can cause serious damage to the system. In case of an over-voltage or over-current situation, a light or sound alarm is activated to alert the operator, and the relay is then automatically deactivated. In addition, the 4554 offers an adjustable hysteresis adjustment knob, enabling the user to set the required level of input current or voltage.

The 4554 80R monitor has a wide selection of features, including a dual loop timer with adjustable time delay for output signal, a digital display and LEDs to indicate operating status, an isolated operation mode, and adjustable trip-points for over-voltage and over-current. Additionally, it can be connected in series with other 4554 units, allowing for multi-channel monitoring in high-current applications.

The 4554 80R monitor can also be used to monitor inverters, power converters, and batteries, providing feedback to an external control system. It is suitable for a wide range of applications such as industrial automation, renewable energy systems, distributed energy systems, commercial building management systems, electric vehicle charging systems, and other high power and current applications.

In summary, the 4554 80R monitor is an invaluable tool in the power and energy industries, providing a reliable, accurate, and easy to install solution to monitoring and controlling critical voltages and currents. With its multiple features, wide range of features, and reliability it is an ideal choice for any application that requires monitoring of current and/or voltage levels.
